Darknet, associated with the website http://pjreddie.com, is an open-source neural network framework primarily used for computer vision tasks. Developed by Joseph Redmon, Darknet is written in C and CUDA, which makes it highly efficient for performance-intensive tasks. It is best known for its implementation of the YOLO (You Only Look Once) family of object detection models, which are designed to perform fast, accurate, and efficient object detection in real-time. The platform is widely used in research and practical applications due to its speed and ease of use. Its source code and various versions, including YOLOv3 and YOLOv4, are available for users to modify and deploy their own models on images and video data.
